No idea what that error message is. I manually linked your accounts, and things look normal to me from here. Can you check if everything is working as expected?

Could it be possible that, because the accounts were already linked the webapp is simply lamenting that this is already done?

Also, what is the best way to verify that this is in fact the case, namely that the two accounts are linked?

Thanks!

You can check by examining your account's identities: https://chromium-review.googlesource.com/#/settings/web-identities

(If you have PolyGerrit enabled, you will need to disable it for this, as a PolyGerrit identity view doesn't exist ATM.)

Your theory seems plausible; however, I'm not too familiar with the Gerrit linking internals. If you'd like to dive deeper, I suggest that you contact the GoB team: http://go/gob-ticket

Ok, disabling the PolyGerrit indeed shows both accounts listed in identities when looking at the page using the @google.com account. When I try to access the page using the @chromium.org account I get an error message that says "armax@chromium.org has already been registered under a different account" which at this point I assume is WAI? If that's the case the bug can be closed.

If it shows the accounts as linked, then this bug is fixed. If you have any issues using services, please file a new separate bug.
